WASTE-VALVE FOR WATER AND STEAM PIPING SYSTEMS.

SPECIFICATION forming part of Letters Patent No. 586,779, dated July 20,1897. Application filed August 18, 1896. Serial No. 603,127. (No model.)

T0 (all wiz/0m it may concern.-

Be it known that we, HORACE F `-iLK NEU- MEYER, residingl at Macungie,in the county of Lehigh and State of Pennsylvania, and JONAS FRANCISYOUNG, residing at Niagara Falls, in the county of Niagara and State ofNew York, citizens of the United States, have invented a new and usefulTaste-Valve for Water and Steam Piping' Systems, of which the followingis a specification.

This invention relates to waste-valves for use in connection with waterand steam piping systems; and it has for its object to provide a new anduseful valve of this character especially well adapted for use inconnection with hydrants, whereby the service pipe or pipes can beautomatically drained of surplus or standing` water therein, which is ofconsiderable importance in cold weather to prevent freezing and theconsequent annoyances.

lVith these and other objects in view, which will readily appear as thenature of the invention is better understood, the same consists in thenovel construction, combination, and arrangement of parts hereinaftermore fully described, illustrated, and claimed.

ln the drawings, Figure l is a vertical longitudinal sectional view of awaste-valve constructed in accordance with this invention and shown inits normal position for draining surplus water in a hydrant or pipingthereabove. Fig. 2 is a similar view on the line 2 2 of Fig. l, showingthe valve closed to permit a free passage of liquid therethrough withoutwaste or escape thereof. Fig. 3 is a similar view to Fig. 2, showing amodified form of valve without the use of springs. Fig. l is a sectionalview of the valve, showing an arrangement of the parts to adapt thevalve for use in connection with steam-pipes for draining from suchpipes the water of condensation after live steam is cut ott.

Referring to the accompanying drawings,

the numeral l designates a valve-casin g preferably made in sections andcomprising the separate casing-sections 2 and 3, the casingsection 2being interiorly threaded at one end, as at l, to receive the reducedeXteriorlythreaded neck 5 of the section 3, but the casing may be formedof one casting, so that the and in this case the pipe-section 7, tted inthe lower end of the valve-casing, is joined with or leads from theordinary hydrantvalve, which is opened and closed in the usual way tocontrol the flow of water, and in this adaptation of the waste-valve thepipe-seetion 7, fitted in the upper end of the valvecasing, forms a partof the hydrant and leads to the discharge-spout thereof, so with thisexplanation it is believed that the arrangement of the valve in the lineof piping will be understood.

Referring particularly to Figs. l and 2 of the drawings, thevalve-casing l is provided intermediate of its ends with an interiorannular valve-seat 8, below or at one side of which the valve-casing isformed with a cylindrical guide-bore 9, while above or at the oppositeside of the valve-seat 8 the casing is provided with an enlargedvalve-chamber l0, directly above which and within the outlet or deliveryneck of the casing the latter is provided with a transverselyarrangedwaste pipe or passage ll, opening at its opposite ends, as at l2, at theoutside of the valvecasing and provided centrally between said open endsl2 and in one side with a drainport 13, through which the surplus orstanding water above the valve is designed to pass into the pipe orpassage ll and thence to the exterior of the valve-casing l. p

The transversely-arranged waste-pipe ll is sufficiently small indiameter so as not to interfere with the free iiow of water through theoutlet coupling-neck of thc valve-casing, and arranged to play withinthe enlarged valve-chamber l0, below the waste-pipe l1,

ICO

is a hollow cylindrical plunger-cup 14. The hollow cylindricalplunger-cup 14 is slidably mounted to work in the cylindrical guidebore9 of the valve-casing, and is provided with a closed end 15, having anannular valveshoulder 16, adapted to work onto the interior valve-seat 8when the plunger-cup is in its normal closed position. The closed end 15of the plunger-cup 14E is further provided with small relief openings orperforations 17 and with a central pin-opening 18, adapted to slidablyreceive therein a movable valvepin 19, provided With a disk head 2G atone end, which works below the closed end 15 of the plunger-cup, andopposite its disk head 20 the said valve-pin 19 is provided with a point2l., adapted to seat itself in the drainport 13 of the pipe 11. Apin-adjusting spring 22 is coiled on the valve-pin 19 and is connectedat one end to such pin and bears at its other end against the closed end15 of the plunger-cup, so as to normally project the pointed end of thepin beyond the closed end of the plunger-cup and in close proximity tothe drain-port 13 in alinement therewith. The said plunger-cup isfurther provided in diametrically opposite sides between its ends withthe enlarged side ports 3, which are sufficiently large to permit a freeflow of the liquid therethrough and thereby not decrease the volume ofwater passing through the pipes connected with the valve-casing.

Assuming the construction described to be used in connection withhydrants, the parts of the valve normally assume the positionsillustrated in Fig. 1, but when the hydrantvalve is opened the waterenters at the lower end of the valve-casing and passes into the hollowplunger-cup 14. The pressure of the water raises the plunger-cup andcarries the point of the valve-pin into the drain-port 13 to close suoliport immediately in advance of the ports 23 being uncovered by passingabove the interior valve-seat S. The press ure of the water continues.to elevate the hollow plungercup until the ports 23 are completelyuncovered to allow the water to freely pass through the line of pipingand the valve-casing to the point of use without escaping through thedrain-pipe 11 of the valve-casing, it being understood that while thewater is passing through the valve-casing there can be no Waste, becausethe pressure against the hollow plunger-cup is constant and keeps thevalve-pin seated in the drain-port of the wastepipe. When the water isshut off, the weight of the column of water above the valve, with theaid of the spring 22, instantly forces down the plunger-cup, and it inturn engages with the disk head 2O of the valve-pin and draws the pointof said pin out of the drain-port 13, thereby allowing all the waterabove the valve to escape through said drain-port and the Waste-pipe.Vhen the supply of Water is cut off and the plunger-cup is closed ontoits valve-seat 8, the small relief openings or perforations 17 allow thewater to quickly pass through the same, so as to reduce the resistanceoffered to the quick closing of the plunger-cup and the consequentuncovering of the drain-port 13, as will be readily understood by thoseskilled in the art.

In Fig. 3 of the drawings is illustrated a modification of the valve inwhich the use of a spring in connection with the valve-pin and theplunger-cup is entirely dispensed with, and in this modilication of theinvention the valve-pin 19 is provided directly adjacent to its point 2lwith a stop-collar 25, adapted to engage with the upper side of theclosed end of the plunger-cup to limit the downward movement of thevalve-pin when it is uncovering the drain-port and to hold said valvepinin a proper position. In addition to being provided with the collar 25the valve-pin 19 in the modification referred to is provided at itslower'end with an enlarged disk head 26, which is of a diametersubstantially agreeing with the internal diameter of the plungercup, soas to form a piston loosely working within said plunger-cup, and whenthe collar 25 of the valve-pin 19 rests against the closed end of theplunger either in its elevated or lowest position the periphery of thedisk head 26 should project slightly belowl the upper edges of the sideopenings 23 of the valvecasing. I

In the modified construction just described the water on being admittedto the hollow plunger-cup first impacts itself against the disk orpiston head 2G of the valve-pin and immediately forces the point of thevalve-pin into the drain-port 13, so as to close such port, and afterthis operation occurs the pin remains stationary while the pressure ofthe water forces the hollow plunger up to a height sufficient to uncoverthe enlarged side ports 23 and allow the free and uninterrupted passageof the liquid or water through the valvecasing.

In the construction referred to the operation of the valve is positive,and no matter how slight the pressure of the water may be the waste-pipewill be closed first, so that no water can escape until the hydrant isshut off, and, furthermore, should the valve controlling the inlet ofwater into the casing 1 of the waste-valve fail to operate at any timeforany reason the defect will be immediately known, as the automaticwaste-valve will be instantly closed, and water instead of wasting intothe ground will lill up the hydrant and attract attention by wasting outof the spout.

The preferred forms of the invention and the manner of using the samehave been described; but when the valve is used for the purpose ofdraining water of condensation from steam-pipes after the live steam iscut off it is necessary to place the valve below the steam-pipe andinvert the parts, as illustrated in Fig. 4 of the drawings. In thisarrangement of the valve it is necessary to provide IOO IIO

for normally holding the plunger-cup closed on its seat S, and toprovide for this a spring 27 is interposed between the closed end of thecup and the shoulder of the casing, formed at one side of Idiewaste-pipe ll. lVhile the movable valve-pin 19 might be employed inconnection with the plunger-cup when supported by the spring 27, suchplunger-cup may be provided at its closed end with a fixed valve-point19a, adapted to seat itself in the drain-port 13 and subserve the samefunction as the valve-pin 19, hereinbefore fully referred to.

The operation of the construction illustrated in Fig. 4c is in allrespects similar to the operation of the valve described in connectionwith Figs. l, 2, and 3, and at this point it will be noted that while inFigs. l and 2, and also in Fig. 3, no spring is necessary for theclosing of the plunger-cup onto its seat still a spring similar to thespring 27 may be employed to insure this operation, and various changesin the form, proportion, and the minor details of construction may beresorted to without departing from the principle or sacrificing any ofthe advantages of this invention.
